Any Council that is fluoridating above 0.7ppm is out of step with the US DHHS recommendation on target fluoride concentration announced in April 2015. Auckland Council followed this recommendation in January 2016. Fluoride Free NZ’s recommended concentration target is 0ppm.

The NZ School Dental Statistics are the most robust set of data we have on dental health in New Zealand. The Ministry of Health have now published the 2015 data which show no difference in decay rates between fluoridated and non-fluoridated areas.
